Hey I couldn't find what I was looking for searching. The only thing I haven't had time to do to finish my lq4 swap completely is hook up the factory tach. I have a escalade cluster on the way so it would be a good time to do it.
So I will need to have the pulses changed in the tune for the tach to read correctly right?
And also where exactly do I need to run the tach signal? Straight to the cluster? Thanks - Josh
More specifics will help, what year pcm, what year cluster?
Usually you go straight from the tach output wire to the tach.
Yes, output pulse can be changed in the pcm.
It's 0411, 99 model esky cluster (direct swap for 95).
tach output from the pcm , straight to the tach input wire on the cluster.
Ok and I will need you to change the pulses in the computer for that to work right?
ya, put both values at "3"
Thank you! I will call you guys tomorrow
